Pella window crank is too small

We have 2 windows made in 1970 and also have windows made by Pella with crankhandle after 1990.The difference is the inside—hole size of 7/16 inch—slightly bigger than 3/8 inch hole in models after 1990.

1009 and 1011 are photos of 1970 crank handles and 1012/1013 are from 1993 windows with crank handle.Pella carries 3/8 inch inside crank handles.But that does not fit into 1970 windows .

It is amazing—rest of dimensions of handle are 100% same—outside dimensions.It is inside—old one were 7/16 inch—1/16 inch bigger than newer –from inside.

If you can find 7/16 inch from inside –that will be great.

Thanks for posting! The older Pella handles were made with the same dimensions as the new 39-109B. It sounds like yours is just worn out. If the new one isn't working it might just be tight. You can try to gently tap it on with a hammer, but ultimately it should fit.

Tom,Thanks.

Pella sent me Crank handle X-429 thru their Sales Rep. He tried to push it--DID not use a hammer.It wouldn't go in.
